MANUAL CLIMATE CONTROL

E217902

Fan speed control: Adjust the volume of air circulated in the vehicle.

A

Power: Press to switch the system on and off. When the system is off, it
prevents outside air from entering the vehicle.

B

Air distribution control: Press to switch airflow from the windshield,
instrument panel, or footwell vents on or off. You can distribute air through any
combination of these vents.

C

Note: At least one of these buttons remain on while the system is on.

Recirculated air: Press to switch between outside air and recirculated air. The
air currently in the passenger compartment recirculates. This can reduce the
time needed to cool the interior and reduce unwanted odors from entering your
vehicle.

D

Temperature control: Controls the temperature of the air circulated in your
vehicle.

E

MAX Defrost: Adjust to switch on defrost. Outside air flows through the
windshield vents and air conditioning automatically turns on. You can also use
this setting to defrost and clear the windshield of a thin covering of ice. The
heated rear window also automatically turns on when you select maximum
defrost.

F

Note: To prevent window fogging, you cannot select recirculated air when
maximum defrost is on.

MAX A/C: Adjust for maximum cooling. Recirculated air flows through the
instrument panel vents, air conditioning automatically turns on, and fan
automatically adjusts to the highest speed.

G

A/C: Press to switch the air conditioning on or off. Air conditioning cools your
vehicle using outside air. To improve the time to reach a comfortable
temperature in hot weather, drive with the windows open until you feel cold air
through the air vents.

Note: In certain conditions (for example, maximum defrost), the air conditioning
may continue to operate even though the air conditioning is switched off.
